Application filedy April S, 1924.

To @ZZ whom t may concern:

Be it known that a citizen of the United States, residing at Lafontaine, in the county of Wilson and State of Kansas, have invented certain new and useful Improvements in Pumping Systems, lication.

This invention rela-tes to a pumping system, more particularly to a compressed air operated controlling device for the lifting step ofthe system, and the invention has for its object to provide, in a manner as hereinafter set forth a pumping system including means whereby compressed air is utilized for the lifting of fluid such as water or oil, from a lo-wer to a higher level for service purposes and furthermore including means operated by compressed air for automatically controlling or regulating the lifting step of the system.

A further object of the invent-ion is to provide a pumping system, in a manner as hereinafter set forth, dently operated from a source other than directly by the lifting fluid, under such conditions the conduit for conducting on the liquid suoli as oil or water, from the source thereof can be tapped `for service purposes at any point, or as many points as may be desired and further whereby the controlling or regulating device, which 1s operated from compressed air will not freeze as would be the case if such device was operated from the liquid fuel;

A further object of the invention is to provide a pumping system, in a. manner as hereinafter set forth, with a compressed air operated regulating and device for the lifting step of the pump and whereby said device can be placed in proximity to the source of fluid,`so as to obtain i i great saving of air pressure when exhausting the pressure to reillthe fluid collecting tank arranged at the sourceof the fluid. Y

A further object of the invention vis to provide a pumping system, in a manner as hereinafter set forth, with a fluid controlling tank provided with a spring controlled piston to set up a suction action to provide for the expeditious filling of the fluidv collecting tank.

A further object of the inventionl is to provide, in a manner as hereinafter set forth, a collecting tank and a compressed air I, JAMns G. HAMPTON,l

Figure l is a sectional elevation of a modified forni of fluid controlling tank.

Figure 5 is a fragmentary view in side elevation, illustrating the liquid conducting conduit provided with means to prevent the exhaust of pressure from the compressed air storage receptacle.

Referring to the drawings in detail, l and 2 denote a pair ofspaced vertical standards connected .intermediate their ends by a combined brace, supporting and guide bar 3, lThe upper ends of the standards l, 2, are connected together by a combined brace and guide bar d. The standards l, 2; and bars 3, 4 provide asupportingframe.

the fluid collecting tank hasl The lower end of the standard 1 has tixedly secured thereto an inwardly extending coupling member 5 having a reduced threaded terminal 6. The lower end of the standard 2 has iixedly secured therewith an inwardly extending coupling member 7 having a reduced threaded terminal 8. Secured to the reduced terminal 6 is a four-way coupling having the vertical legs thereof indicated at 9, 10, and the horizontal legs at 11, l2. The terminal 6 is secured to the horizontal leg 12 and closes the same. Secured to the terminal 8 is a four-way coupling having the vertical legs thereof indicated at 13, 111 and the horizontal legs at 15, 16. The terminal 8 is secured to the leg 16 and closes the same. The legs 9, 10, 11 and 12 of that four-way coupling secured to the coupling member 5, are interiorly threaded. The legs 14, 15 and 16 of the four-way coupling secured to the member 7 are interiorly threaded. The four-way coupling secured to the coupling member 5 provides a valve chamber 17, and the four-way coupling secured to the coupling member 7 forms a valve chamber 18.

The four-way coupling secured to the coupling member 5 is indicated generally by the reference character 19, and the four-way coupling secured to the coupling member is referred to generally by the reference character 20.

Extending at right angles with respect to the four-way coupling 19, as well as threadxdly engaging with the leg 11 thereof is a pipe section 21, having secured therewith a union 22, which provides a valve chamber 23 for a cheek valve 24. rlhe union 22 is provided with an apertured partition 25 constituting a valve seat for the cheek valve 241. The pipe section 21 is connected to one end of the union 22 and to the other end ofthe union 22 is secured a pipe section 26. EX- tending at right angles with respect to the four-way coupling 20, as well as threadedly engaging with the leg 14 of said coupling, is a pipe section 27 which opposes the pipe section 23, and the said sections 23, 27, have their opposed ends connected by a three-way coupling 28, having a vertically disposed leg 29 projecting from the upper side thereof. Secured to the leg 29 is a vertically disposed air regulating valve 30, which is connected to the bottom 31 of a compressed air receiving cylinder which forms an element of the compressed air operated controlling and regulating device for the lifting step of the pump. The valve 30 opens into the cylinder 32, at the bottom thereof, as at 33, and provides means for regulating the amount of compressed air supplied to the cylinder The compressed air controlling and regulating device for the lifting step of the pump not only includes the compressed air receiving cylinder 32, but further comprises a piston head 34 operating in the chamber 35, formed by the cylinder 32 and having connected therewith a substantially elongated piston rod 36 which extends through the closed head 3T, at the upper end of the cylinder 32 and further a substantial distance above said head. The piston rod 86 passes through a guide opening 38, in the bar 3, and also through a guide opening 39 in the bar l1, as weil as through a collar 110 secured upon the upper face of the bar L1, by the hold-fast device d1.

idjustabiy connected to the rod 36, above the bar 3, s-.ipporting collar 112, for one or more weights 113 acting as a means to maintain the piston 33 in a lowered position, and the lifting of the latter by the incoming compressed air is had against the action of the weights d3.

Secured to the bar 8, as well as projecting upwardly therefrom and in proximity to the piston rod 3G, is a yoke-shaped support t, carrying a shiftable shaft 45, provided with a cam 46 and formed with a crank arm l-T. rlie outer end of the cranl; arm 4-7 is connected by a coiled spring L18 to the piston red 36, as at L19.

Fixedly secured to the bar 8, at a point between its center and the standard 2, is an interiorly threaded i'ianged bushing 50, which extends through the bar 3, as well as proliects upwardly therefron. The bushing 50 is also peripherally threaded for the engagement therewith of a clamping nut 51, whereby the latter in connection with the flange 52 of the bushing will clamp it to the bar 3. Threadedly engaging with the bushing 50 is a vertically disposed post 53, carrying an adjusting nut 64, for a flanged. holding member 55. rThe post 53 has a shiftable disk 55 mounted thereon, and interposed betweenv the disk and the member as well as surrounding the post 53, is a coiled expansible and contractile spring 57.

Pivotally connected at one end, as at 58, to the standard 1, is a lever arm 59 of a length to extend in close proximity to the standard 2. rEhe lever arm 59 is provided with openings 69, G1 and 32. The cam 116 is of quadrant shape and when in normal position has one of its side edges 62 seated upon the lever arm 59. Then the cam d6 is shifted to operative position its curved edge 63 rides against the lever arm 59 and depresses it. The earn et@ is shifted by trie piston rod 36 when the latter moves upwardly. rlhe normal position of the cam and piston rod is shown in full lines, Figure 2, and the shifted position of the cam 46 is shown in full lines, Figure rlhe post 5G extends through the opening 61 in the lever arm 59, and the latter when in normal position as shown in Figure i?, rests on the disk 56. rihe shifting downwardly of the llever arm 59 is had against the action of the spring 5T. The

Cil

The air compressed controlling and regulating device for the lifting. step of the pump associates With an intake valve mechanism and an exhaust valve mechanism 'for theV purpose of controlling the supply and exhaust ot the compressed air which is employed forl pumping or lifting the fluid, and the said device normally maintains the exhaust valve mechanism in closed position and 'further synchronously operates said valve mechanisms to close the intake valve mechanism and to open the exhaust valve mechanism.

The intake valve mechanism consists of a pair of oppositely extending spaced bushings G3, 64. The former has threaded engagement with the leg 9 of the 'four-Way coupling 19 and projects upwardly therefrom, and the latter has threaded engagementvvith the leg l0 of the tour-Way coupling 19 and depends therefrom. The hushing 63 has a centrally disposed opening 65, and the' blushing 64 has a centrally disposed inlet port 66. The inner end oit the bushing G3 provides a valve. seat 67 and the inner end of the `oushing 64 provides a valve seat Extending through the bushing 63 and having its inner end arranged in the valve chamber 17,' is a` vertically disposed valve stem 69 of a length sufficient to extend through the har 3 and also through the opening G0 and above the arm 59. rEhe inner terminus of the stein 69 has secured theretor a valve 70 for closing the supply of compressed air through the valve chamber l?, and said valve 70 when the stem 69 is in its lowered position engages the seat 68 and closes the intake. port 66.

The valve stem G9 has secured to the inner terminal portion thereof, in spaced relation with respect to the valve 70, a valve 7l, adapted to engage the seat 67 to close the opening 65 through which the stem 69 passes. The valve 7l is normally in engagement" with the seat 67, and the valve 'T0 is normally off its sea-t 68 whereby under normal conditions the intakeport G6 will he opened and the opening 63 closed. The valves are maintained in `the position juststated, through the medium of a controlling spring T2 which is mounted on the stem 69, and is interposed between the bushing 63 and a stop element 73, adjustably secured to the stem G9 through the medium of a set screw 74;

The rod 69, near its upper end, is provided \vith a. threaded portion 75, and adjustaloly engaging With the threaded portion, is a stop 75 which ahuts against the lever arm 59, whereby when the lat-ter is shifted through they action of the cam 4,6,

The reference character YS denotes a cornp=ressed air storage receptacle having leading` therefrom a compressed air supply conduit consisting of a vertically disposedpipe branch 7 9, which communicates with the receptacle 7S and has interposel therein a cutoil valve 80, a three-nay coupling Si, and theupper end of the branch i 9 a gauge 82 connected therewith. The compressed air supply conduit further includes pipe branches 83, 91, and the pipe branch' S3 has interposed therein a three-Way coupling 84, a cut-ofi' valve 85, a threeavay coupling S9, a union 87, ay tour-Way coupling SS'and a cut-oil 89. rlfhe pipe hranch 7G is connected to the three-Way coupling 8d. The gauge 90 is connected with the three-Way coupling 8G. 'he 'tour-Way coupling 88 is interposed between the union 87 and the cut-oit 89.

T he pipe branch 83 extends at right angles to the pipe branch 79, and. the pipe hranch 9i extends at right angles with respect to the pipe branch S3 a-nd'is connected to the lower vertical leg of the four-Way coupling 88. f

The exhaust valve mechanism comprises a cylindrical cast-ing' 92, formed with an angle-shaped passage 93, having' the vertical leg thereoiQ opening into the valve chamber 18. The casting 92 extends into the leg 15? ot the four-way coupling 20 and has its inner end shaped to provide a valve seat- 94e.k rlhe casting 92 is peripheraliy flanged, as at 95, and ywhich seats on a lateral annular yflange 96, at the upper end ot the leg 13'.

The casting 92 projects upwardly from the leg i3 and is inclosed hy a c) indrical casing 97, flanged at its upper anu loiver ends, as at 98, 99, respectively. The flange 99 seats on the {iange 95. The iianfles 95, 9G and 99 are suitahly secured together. @ne side of the easing" 97 is lioruied with' an opening 100 and alsoivith an annular iiange lOl registering with said opening, Extending througl'i. the flange 10i and connected to the casing 93, is a discl'iarge `pipe i9?

r1`he source or iluid or water suppl); is indicated at 115, in which is sulniierged a fluid collecting tank consisting ot a cylindrical body portion 110, formed with a hottom 117, havingl a centrally disposed openingl 11S and a collar 119 depending; therefrom and surrounding the opening .113. The body portion 116 is flanged at its top, as at 120, and secured to the flange 120 by hold-tast devices 121, is a closure plate 122 having` a centrally disposed opening' 123 and a ve; cally disposed collar which surrounds the opening 12. The body portion 11G has a pipe branch .125 connected therewith aboce the bottoni thereo't and said pipe branch 125 communicates with the interior o1' the body portion 116 and 'terms a section ot the fluid conducting conduit through which fluid is lii'ted troni lower to a higher level for service purposes. The fluid conducting` conduit 'further includes a pipe branch 126, a pipe branch 127 and a pipe branch 123. The pipe branch 127 extends at right angles with respect to the upper end oi the pipe branch 126 and has connected therewith, intermediate its ends, a stand pipe 123. A faucet 129 is secured to the tree end of the pipe branch 127. The pipe branch 120 has interposed therein a by-pass 130 provided with a cut-oli 131 and a check valve 132.

the

ing the tluid thereto. The intake pipe 133 has a tilter 134 at one end and said nie 133 is further provided with a check valve 135.

Arranged within the body portion 116 is a spring' controlled piston head 130 to which is attached a piston rod 137 which extends up into the pipe branch 91.

Secured to the collar 124 and projcctiff upwardly therefrom is a cylindrical casing' 133, which is connected to and communicates with the lower end of the pipe branch 91. The couplingl element 139 is employed for connecting the lower end orn the pipe branch 91 to the upper end ot the casing 13S. 1Within the lower end of the casing 138 is secured a. stop collar 140, and seating thereon a coiled spring 141 which abuts against the disk 142, secured to the stem 137. The downward movement oi? the piston 136 is had against the action ot the spring 141 so that when pressure is relieved upon the top of the piston 136, the spring 141 acts to f wete the piston 13G, under such conditions piston 130 will set up a suction action and draw the lluid into the body portion 110 which provides what may be termed a luid collectingT chamber 143. The check valve 135 does not interfere with the intake or the :liu id into the chamber 143, but closes the lower portion of the intake pipe 133 when the piston 136 moves downwardly in the chamber 143, and the downward movement ot the piston 136 is had through the supply ol: compresset. air thereagainst d such downward movement provides ttor me i'ttina` ot the fluid up through the fluid conducting` conduit.

rlie fluid controlling;Y tank, as shown in nre 1, is employed for deep wells from two hundred to one thousand ''eet deep, but ior shallow wells troni twenty to two hundred feet deep a larger tank would be em ployed. 1t is possible with wells ranging from ten to Fifteen feet deep to place the suction tank above the surface ot the lground. dl hen usingthe system in connection with a shallow well, the torni ot' collecting' tank shown in Figure 4 would be employed and which is referred to generally b v the reference character 144. The opening` in the` body portion of the tank to which the pipe branch 125 is connected is closed by a plug 145.

Although the fluid collecting tank is shown ot the successive type, yet if desired the tank can be set up without the suction feature included.

Vith reference to Figure 5, the fluid conlili) ducting conduit is provided with means for closing the apparatus when a'well is pumped dry, thus protecting Athe storage pressure. For this purpose the fluid conducting conduit, which is indicated at 146, has interposed therein a fluid receiving chamber 147, provided with an outlet pipe 148, controlled by a iioat operated valve H9. Communicatl ing with the upper end of the chamber 147 is a pipe branch 150 which opens inte a compressed air cylinaer 151 in which is arranged a pisten 152, to which is connected a piston rod 153. which projects from the cylinder 151 and is previded at its outer end with weights tleinmunicating lwith the upperend of the cylinder 151, through a head member 155, a discharge pipe 155. The piston red operates through the head member 155. Leading from the chamber l-li' to the pipe 156 is a pipe branch 15S, pro- 'ided with a cut-olf 159.

The piston 151 is polygonal in contour, thus allowing low pressure to escape around the saine and out through the discharge pipe 156. rhe upper end of the piston 152 constitutes a valve adapted to engagea valve seat 160, formed at the lower end of the head member 35 for the purpose of shutting oil communication between said member ane the interior of the cylinder 151. When the piston 152 is raised by high pressure it engages the seat 160 and closes the head member 155 tothe cylinder 151. lf the well is pumped dry or fluid fails to enter the liquid collecting tank at the source of supply., a direct line from the receptacle "Z8 to the cylinder 151 and tank 147 is provided and unless some means is employed to close such line the receptacle 78 would soon become exhausted of compressed air. rlhe piston 152 is provided whereby high pressure will shift the same upwardly to close the head member and arrest the discharge of cenipressed air. "When no liquid is supplied te the tank 11i?, the lluid operated valve closes the pipe 148, under such conditionsv the compressed air exhausts through the pipe 15G. The vali/e or cut-elf 159 is normally closed and is employed for exhausting the pressure when it is desired to start the operation of the apparatus.

The `Jelunie of air pressure admitted through the intake valve is governed by the faire 80. The spring controlling exhaust Valve shculd be set to throw oil at a pressure just a little above the spring pressure of the suction liquid tank which may be not more than teu or twelve degrees in most cases. The above applies to when the air follows the liquid out the liquid pipe. Then the liquid is all forced out of the tank into the vertical liquid pipe, the air pressure builds up as the liquid rises, if the valve 80 is roperly adjusted, and the air will now begin raising the piston in air cylinder and low the lil uid u 3 the ive. ln this case no check valve in pipe near water tank is required. rlhe by-pass valve is all that is required.

rlhe valves 85 and 89 yare used at will when the apparatus is out of order, or for adjusting spring' pressure on exhaust valve stem, also weight pressure on air cylinder connecting rod, guidedby air gauge 90.

New pressure is cut oli but is built up a little above the required pressure for lifting this amount of liquid, therefore, its expand-v f ing power will start the liquid flowing out, reducing the load against the air. The pressure of the air is soon destroyed except the back pressure produced `by suction sprin'.

`Now all of the liquid is expelled from pipe,

or if some is left at the time the exhaust comes on, it will remain in the plpe held by air and check valves until the next load of pressure is admitted. Will do no harm to close faucet at any time. The air cylinder valve and weights may also be set so as to open just after the water leaves the vertical liquid pip-e at surface entering the horizontal one provided the vertical pipe opening is reduced at surface, that is, vertical pipe onehalf inch, horizontal pipe three-eighths inch. This will cause air pressure to build while the piston in thev air cylinder rises to cut olf pressure. Then the volume of pressure existing in pipes and liquid tank will expel the liquid now in the pipe. llVith this systeni one-half more liquid is lifted with the same tank of air as under all of the air pressure exhausting systems one-half of the pressure required to-.lift water is exhausted or wasted. Thus a great saving of power. Also by using low pressure air danger of `leading joints is reduced.

yWhen suction piston in Vliquid tank is forced down to bottom all of the liquid in said tank is now expelled from tank into vertical liquid pipe through pipes 125 and 128r that all of the liquid now is in the vertical pipe but not yet raised to surface, say that it only fills this pipe feet in height. Next the air pressure follows up under this liquid load through pipe 125 while air cylinder piston is slowly rising to cut off pressure storage tank, thus raising its load to surface, (that is the upper portion of the 100 feetr of liquid), bythe time air pressure is cut off. Now ytheair pressure being raised a little above required pressure 'soon as prcssrc reduces suflicientlj,VT

for liftingthis load said pressuie will deliver its load to surface or into utilization tank by the expanding` poiver of the air volume contained in liquid tank and piges, without aiuv further pressure from storage tank, it being` cut orf. The surplus pressure, after liquid expelled will pass oilA through automatic at the end of liquid pipe through pipe 150, (loir 1n'essure), liquid pipe being in size in proportion to liqui-i tank.

is the liquid passes out the load is reduced, so is the air pressure, contained in liquid tank and liquid pipe proportionally reduced, thus the exhaust valve iill open a spring to throw open the exha va v closed in the meantime.

rlhe check valves 125, 128 in the pipes 125 and 128 not onlyv prevent the air pressure in liquid pipe from being drawn hack into liquid tank under such piston when it is lifted upvvard by spring, butA also form a footing` or base for pressure to expand against in lifting' its loa-cl after exhaust valve opens.

The foregoing' explains why liquid mav be raised 1000 feet with a pressure of no nere than fifty or one hundred.
